Question

我遇到了以下问题：我想通过使用org.eclipse.test.performance框架来衡量Eclipse插件的性能。我已经创建了一个测试类和所需的代码。

我完全按照本article中的说明完成所有操作，直到“查看数据”，但我仍然没有工作数据库......

正如您在堆栈跟踪结束时看到的那样“DB中没有新的数据点”。如果我从控制台运行此测试，则除了“java.lang.IllegalStateException”之外没有显示任何内容，但没有显示性能测试结果和数据库信息。

org.eclipse.test.uitestapplication的程序参数：

-os ${target.os} -ws ${target.ws} -arch ${target.arch} -nl ${target.nl} -consoleLog
-testpluginsnames com.test.eclipse.performance
-classesnames com.test.eclipse.performance.PerformanceTestCase
-Declipse.perf.dbloc=C:\Users\thupel\MyTestDB
-Declipse.perf.config=build=CRAP;host=LOCAL;jvm=DONTKNOW
formatter=org.apache.tools.ant.taskdefs.optional.junit.XMLJUnitResultFormatter
haltOnFailure=false

MyPerformanceTestClass：

package com.test.eclipse.performance;

import org.eclipse.test.performance.Dimension;
import org.eclipse.test.performance.Performance;
import org.eclipse.test.performance.PerformanceMeter;
import org.junit.Test;
import org.junit.Before;

public class PerformanceTestCase
{

    final static String ID = "sample_ID";
    final static String NAME = "sample_Name";

    public PerformanceTestCase() 
    {
        System.out.println("Constructor called");
    }

    @Test
    public void testMyOperation() 
    {
        Performance perf = Performance.getDefault();
        PerformanceMeter performanceMeter = perf.createPerformanceMeter(ID);
        perf.tagAsSummary(performanceMeter, NAME, Dimension.CPU_TIME);

        long a = 0, b = 0;
        try 
        {
            System.out.println("MEASUREMENT STARTED");
            // measuring
            for (int i = 0; i < 10; i++) 
            {
                performanceMeter.start();
                for (int j = 0; j < Math.pow(10, 7); j++) 
                {
                    a = i + a;
                    b = b + a;
                }
                performanceMeter.stop();
            }
            System.out.println("MEASUREMENT FINISHED, b = " + b);
            performanceMeter.commit();
            perf.assertPerformance(performanceMeter);
        } 
        finally 
        {
            performanceMeter.dispose();
        }

    }

    @Before
    public void setup() 
    {
        System.out.println("Startup called");
    }
}

基本上我自己解决了这个问题。也许这个答案可以帮助有类似问题的人。

首先我做的（可耻的）错了：

-Declipse.perf.dbloc=C:\Users\thupel\MyTestDB
-Declipse.perf.config=build=CRAP;host=LOCAL;jvm=DONTKNOW

是VM参数我把它在eclipse运行配置中放入程序参数中是没有意义的，它们需要作为VM参数。

下载“org.eclipse.test.performance”框架的源代码后，我看到在“org”下添加了名为“org.apache.derby.core”的数据库信息交换所需的可选插件.eclipse.test.performance“插件的依赖项。 eclipse wiki上的教程说我应该把它命名为“org.eclipse.derby”，但性能插件不会发现这个，显然它的名字错了......

最后，在我将所有derby jar添加到“org.apache.derby.core”并再次运行性能测试用例后，数据存储在一个名为“MyTestDB \ perfDb”的新derby数据库中。

暂时问题解决了。：）

Eclipse性能测量框架，Derby数据库不起作用
